2023 Chevrolet Blazer

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 Blazer.

The 2023 Chevrolet Blazer takes 6.0 quarts of 5W-30 or 0W-30 oil, and its reliability record shows 37 total owner complaints with the power train as the leading concern alongside two recalls. In the context of the model's complaint history spanning 1990 through 2026, this model year sits well below the peak of 1,418 complaints recorded in 1995 and far above the single complaint logged for 2026, placing it in the lower-mid range of the nameplate's documented issues. That positioning suggests the 2023 Blazer carries a moderate complaint burden relative to its predecessors, with power-train reports and a pair of recalls defining the primary areas for researcher attention.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 60,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2023 Chevrolet Blazer recorded 37 complaints, 2 recalls, and 567 technical service bulletins, with the most frequent complaints involving the power train (7), service brakes (3), engine (3), and forward collision avoidance (3). Within the current generation beginning in 2019, there is a clear downward trend in complaints, which peaked at 211 in 2020 before steadily declining. The 2023 model falls toward the end of this arc, showing a significant improvement over the 182 complaints reported in 2019 and 123 in 2021. When compared to the following year, 2023's complaint volume is nearly identical to 2024's 38 reports. While three crash complaints were noted, the data does not specify the root cause of the reported power train or braking issues. Given the stabilizing complaint rates and the overall downward trend for the generation, this is a good year to buy.
